Bosch washing machine does not fill with water

Notice that the washing machine does not simply fill with water - the machine does not hum, the drum does not fill, and the cycle does not start. All this suggests that there has been a malfunction in the equipment, without which the washing will not start. Several breakdowns at once can lead to the lack of a set. To continue washing, you will have to carry out a Bosch diagnostic, determine the nature of the malfunction and correct the problem. A list of errors and step-by-step instructions will help with this.

What failures caused this?

An empty Bosch machine will not wash clothes, so it is necessary to correct the situation quickly. First, you should check whether there is water in the pipes - it is possible that the central water supply has been turned off. The second step is to make sure that the hatch door is tightly closed, since if the drum is unlocked, the system does not activate the UBL and does not give a command to fill the tank.

• If everything is in order with the water supply and the door, we begin advanced diagnostics. Several malfunctions can lead to problems with water intake: from a crushed hose to damage to the control board. It is not difficult to determine the “culprit” if you know the main “symptoms” of typical failures and breakdowns.
• Broken filling valve. If it was previously noticed that the powder from the cuvette is not completely washed out, then there is a high probability that the part has failed. It is easy to verify that it is working just plug the element into the network and apply 220V to it. A working valve should close and click, and if there is no response to voltage, replacement is necessary. We check two devices at once.
• Clogged mesh. The machine does not draw water if the inlet filtration system is clogged. The machine will try to fill the tank for a long time and make a characteristic hum. The problem is eliminated by dismantling and cleaning the mesh.
• Clogged filter. A contaminated coarse filter often prevents the intake. The nozzle needs to be cleaned.
• Failed pressure switch. If the level sensor is faulty, the control board cannot monitor the degree of filling of the tank and, for safety reasons, does not start drawing water. To confirm the breakdown, you need to remove the top cover of the machine, find the device, disconnect the connected tube, insert a hose of the same diameter and blow. A working pressure switch will respond with clicks, while a broken one will “remain silent.” In the second case, the part must be removed from the housing, inspected, and cleaned. The fitting is clogged, and after blowing it will come back into shape.
• Broken inlet hose. It is possible that the rubber band is pinched and does not allow water to “pass” to the Bosch.
• Damaged pressure switch hose. During operation, it loses its tightness, wears out and allows air to pass through, creating problems with pressure and operation of the level sensor.
• Faulty drain pump. If the board has detected a pump failure, the water supply will not start. You must first repair or replace the part.
• Broken board. If there are problems with the “brain,” the washing machine will not work at all, and it will not draw water.

If the Bosch washing machine has a display, then if the kit is missing, you should pay attention to the error code that appears. By deciphering the combination using the factory instructions or the Internet, you can narrow down the range of problems and quickly identify the “culprit” of the failure that occurred.

Is it worth getting into the body of the machine?

It is not recommended to repair a newly purchased washing machine yourself. Do not forget that all Bosch models come with a one-year warranty, so it is cheaper and more reliable to contact a service center for professional help. If you open the case before calling a specialist, warranty service will automatically end.

It is another matter when the machine is not covered by warranty. In this case, it is better to try to solve the problem on your own, so as not to overpay the technician for repairs. First, we check whether the central water supply is turned off, and then we make sure that the shut-off valve is open. Next, inspect the inlet hose for damage and squeezing. If there are no visible problems, you will have to “open” the machine and carry out advanced diagnostics.

Let us start looking for the problem.

To restore the functionality of the washing machine, you need to figure out in advance what to do and in what sequence. The first step is to disconnect the washing machine from the power supply and turn off the water supply tap. These are mandatory safety requirements, violation of which is fraught with dire consequences.

Now you can start looking for the cause. Let us start checking with the basics:

• make sure that the water supply tap was opened earlier,
• unhook the inlet hose from the water pipe and drain the remaining water from it,
• We inspect the rubber band, trying to notice defects, cracks, blockages or squeezing.

If no fault is found at the initial stage, we move on. Next in line is a mesh filter. The filter nozzle is installed in the inlet hose and, when clogged, prevents water from “passing” into the machine. To make sure it is clean, you need to:

• Unhook the hose from the machine body,
• Find a mesh,
• Use pliers to grab the protrusion provided and pull the filter out,
• Rinse the mesh under water and, if necessary, clean with a toothpick or toothbrush,
• Return the nozzle to its place using pliers.

The coarse filter must also be checked. This element is mounted after the faucet, so cleaning it will require a couple of keys. One holds the junction with the valve, and the second unscrews the fixing screw. Be prepared for the fact that when completely unscrewed, water will pour out of the hole, so you should place a basin in advance. Under intense pressure, the filter will clean itself - you just need to wait a minute and screw the bolt back.

Climbing under the top cover

The most common culprit for a missing kit is a faulty fill valve. To solve the problem, it is enough to dismantle the old device and install a new one in its place. The only question is the price - in the service center the repair will be estimated at 4-5 thousand rupees, and a replacement with your own hands will cost a maximum of 500 rupees. You can meet the last amount even when purchasing high-quality spare parts.

The upcoming scope of work will not frighten even a beginner - everything is done simply, quickly and without unnecessary risks. You just need to follow the instructions.

• Disconnect the washing machine from the network and water supply.
• Disconnect the inlet hose from the body (do not forget about the residual water, which is best drained into a previously prepared container).
• Unscrew the bolts holding the top cover and remove the panel.
• Find the valve and take a photo of the connected line (this will help avoid problems when connecting back).
• Disconnect the wiring.
• Release all 4 hoses connected to the valve.
• Unscrew the valve fixing bolt.
• Remove the part from the housing.
• Install a new valve in the free space.
• Secure the part with a bolt, bring in the previously removed hoses, tighten with clamps, and connect the wiring.
• Replace the cover.

All that remains is to attach the inlet hose back to the Bosch and open the tap. After that, the washing machine is connected to the network, and any fast program is selected. If the drum begins to fill, it means the replacement was successful.
